I like maintaining things: the Elasticsearch Python clients by day, urllib3 and trustme by night.

I thought about storing comments on GitHub with utterances/giscus, but ended up on Commento. They have a generous free tier, don't track their users, and are trusted by Mozilla.

Free-Threading builds are here to stay. The adoption has been incredibly fast so far. (urllib3 works with free-threading, but still need cryptography to add support before we can test it in CI.)

In 30 minutes, a binary search implementation is sped up by 25x using profiling tools, including L1 cache and pipeline stall analysis. While the tools are Apple-specific, the concepts are general and apply everywhere. https://developer.apple.com/videos/play/wwdc2025/308/12 Jun 2025 17:44 +0000at://did:plc:exqluv56liuk3k6plbiejvey/app.bsky.feed.post/3lrghyak6ic2ihttps://bsky.app/profile/quentin.pradet.me/post/3lr755gxo5k2pIn the past nine months, three companies (Speakeasy, Stainless, and Fern) have collectively raised $49M to bring SDK and docs generation to everyone. Why now? I have no idea. After all, this has nothing to do with AI, and OpenAPI Generator has been popular for years.09 Jun 2025 19:42 +0000at://did:plc:exqluv56liuk3k6plbiejvey/app.bsky.feed.post/3lr755gxo5k2phttps://bsky.app/profile/quentin.pradet.me/post/3lq24vy4sic2sIt looks like mapping the new syntax to the Elasticsearch DSL, which natively supports nested queries and boolean operators, was the easy part. Elasticsearch has lots of features, yes, but it is to support advanced usages like this one!

But before we can have CI, we need cryptography wheels as we use it to generate test certificates.

The highlight for me was @burntsushi.net making `uv pip compile` 3x faster by representing most versions as a single u64 integer, making comparisons much cheaper.
